Dynamic thresholds for the resilience assessment of road traffic networks to wildfires

The severe effects of extreme wildfire events in recent years have shown that the fire suppression approach is not enough to solve the problem. An alternative to dealing with this issue is to accept the impossibility of eliminating wildfire hazards and focus on preparing systems to be more resilient. However, existing decision-making tools...

Metamodel-based metaheuristics in optimal responsive adaptation and recovery of traffic networks

Different emerging threats highlighted the relevance of recovery and adaptation modelling in the functioning of societal systems. However, as modelling of systems becomes more complex, its effort increases challenging the practicality of the engineering analyses required for efficient recovery and adaptation. In the present work, metamodels...

Human actors, a system vulnerability or a capability for adaptation to enhance resilience of transport networks?

Consideration of climate change-induced corrosion by structural codes

The impact of climate change on ambient temperature and relative humidity along with the present CO2 levels are speeding the corrosion process of reinforced concrete structures. The alarming cost of the associated reduction of the service life of structures, which is estimated to cost 3% to 4% of the Gross Domestic Product (GDP) of...

Multi-system intervention optimization for interdependent infrastructure

The wellbeing of modern societies is dependent upon the functioning of their infrastructure networks. This paper introduces the 3C concept, an integrative multi-system and multi-stakeholder optimization approach for managing infrastructure interventions (e.g., maintenance, renovation, etc.). The proposed approach takes advantage of the...

Prescription of maintenance interventions by the new generation of Eurocodes for climate-change resilient structures

The new generation of structural Eurocodes will include climate change adaption measures in order to enhance the climate resilience of infrastructures across Europe. This paper discusses the impact that climate change might have on reinforced concrete structures subjected to corrosion, and the associated challenges of the standardisation of...

Resilience Quantification of Large-Scale Water Distribution Networks: A Probabilistic Approach

The capacity of a community to react to and resist during an emergency situation is highly related to the proper functioning of its infrastructure systems. Improving the infrastructure response and recovery capacity through management and adaptation strategies can help increase community resilience. Infrastructural assets are considered outdated...
